如何将滚动条位置始终保持在视图顶部？

Question

I am making a layout in which I am using a Scrollview to put the stuff in the view. But when in the view, I moved the scrollbar down and then moved to next view, the scrollbar remained at the same position, meaning, at the bottom part of the view. I want to make sure that the scrollbar remains at the top of the view always, by default. This is the XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_centerHorizontal="true"
    android:orientation="vertical" >

    <ScrollView
            android:id="@+id/scrollView1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="90.0dip"
            android:layout_marginLeft="1.0dip"
            android:layout_marginRight="1.0dip"
            android:layout_marginTop="1.0dip"
            android:fadeScrollbars="true"
            android:fadingEdge="none"
            android:fillViewport="true" >

    <FrameLayout

            android:visibility="visible" >

            <ImageView

                android:visibility="visible" />


                <TextView

Please tell me how to do that.

Please tell me how to do that.

Your question is ambiguous. If the ScrollView remains where you scroll after you go to the next/previous question simply use the the method scrollTo on the ScrollView like this when you switch questions:

((ScrollView)findViewById(R.id.scrollView1)).scrollTo(0, 0);

If you go to a new activity and want the ScrollView at the start position then simple place the above line in the onResume method of the Activity .
